4.5 Description of basic functions
4.5.1 Short-term unlock
Short -term unlock is the authorised, time-limited release of the emergency route locking device. During the
short -term unlock time the door can be passed through without triggering an alarm. It is triggered via the inter-
nal key-operated push button or an external control device connected to the 'short-term unlock' input.
4.5.2 Abort with short-term unlock
With continuous short-term the door locks ahead of time when the door is closed before expiry of the short -term
unlock time. This prevents accessibility for unauthorised persons after somebody has passed through the door.
4.5.3 After-trigger with short-term unlock
The unlock time restarts if a short-term unlock is triggered again during the release time.
4.5.4 Pre-alarm
If the release time is exceeded during passing through, an acoustic signal is output which informs the user that
the short -term unlock time has been exceeded. If the door is closed during a pending pre-alarm it is automati-
cally locked and the pre-alarm is reset.
4.5.5 Door alarm
The door alarm is triggered if the pre-alarm time is exceeded. The door alarm must be reset via the internal key
switch or via a short-term release. If the door is closed during a pending door alarm, it is locked and can only
be unlocked again when the alarm has been reset (except with actuation of the emergency button or with
emergency unlock). The door alarm is also triggered with a 'door break-in'.
4.5.6 Unlocked
The current supply to the interlocking element is permanently interrupted. The door can be passed through
without triggering an alarm.
4.5.7 Locked
The interlocking element is fed with current via the door control unit. The emergency route locking device is
'active' and passing through for unauthorised persons is only possible via the emergency button (alarm is triggered).
4.5.8 Emergency unlock
The TZ 320 can be emergency unlocked via the fire alarm system or hazard alarm system (burglar alarm system/
hazard alarm system/smoke and heat venting system). This is a non security-relevant interruption of current
supply to the interlocking element.
4.5.9 Direct release (according to EltVTR)
Security-relevant interruption of electric power supply to the electric locking mechanism via an opening contact
by actuating the emergency button.
4.5.10 Indirect release (according to EltVTR)
Security-relevant interruption of electric power supply to the electric locking mechanism if a further switching op-
eration is triggered upon activating the emergency button via the opening contact which then interrupts power
supply to the electric locking mechanism.
